to provide a device of the above character a rock shaft 31, the inner which will automatically couple and uncouple cars.

Our improved coupling device may be ap` plied to any form of car, but the same is articularly useful in connection with cars employed for transporting coal or the like from a mine to a dump. By the employment of our coupling a car may be run upon a side track and cut loose from the engine or another car without stopping said engine or manually operating the coupling. This results in the saving of time and labor, whereby the cost'of transportation is reduced.

Our invention consists generally in the combination with a coupling of automatic means for operating the same.

V In the accompanying drawing forming a part of this specification the figure is a perspective view of the coupling and associated members.

In the drawings illustrating a preferred embodiment of our invention, the numerals 1 and 2 designate as a whole, cars, which are equipped with the coupling. The coupling comprises cooperating `draw-heads 3 and 4, which have their inner ends bifurcated for the reception of portions of the cars 1 and 2, to which said bifurcated ends are rigidly secured by means of bolts 5 or the like.

Arranged upon one end of the car 2 are spaced brackets 29 whichl are in horizontal alinement and secured to the car by means of bolts 30 or the like. These brackets support end of which is bent to form a crank 32, to the end of'which is secured a chain 33 which is also connected to the upper apertured head 34 of a coupling pin 35. The outer end of the rock shaft 3-1 lis bent to form a crank 35 to which is pivotally connectedthe upper end of a link 36, the

' lower end of which is pivotally connected as at 37 to a push-rod 38.- This push-rod is verdiagonally arranged rods 42.

`above the same by virtue tically disposed and slidably mounted within a bracket 39 which is rigidly connected to the end of the car 2 Vnear one side thereof, by-

means of bolts 40. The rod 38 is further slidably mounted through a collar 41, which is rigidly connected tothe car 2 rIhe push rod 38 carries upon its lower end a yoke 43 between the spaced sides of which is rotatably mounted a wheel 44 as shown in This wheel 44 is ydesigned to engage a supplemental rail 45, which is arranged inwardly of the track rail 46 and elevated of its being arblocks 47. The supplemental ranged upon from its ends torail is inclined upwardly ward its center, whereby gradually elevated.

Attention is called to the fact that the vertically movable pin 21 besides from fulfilling its ordinary function, serves the additional function of returning normal lowermost position, in case the push rod should be raised accidentally. It will thus be seen that the pin 35a is a gravity operated element, which must be in its lowermost position when the cars are coupled, and which serves its lowerrnost posit-ion.

In the operation of the coupling mechanism, assuming that the draw-heads 3 and 4 are connected or coupled, the cars 1 and 2 are then drawn along the track until the sup- Fig. 1.V

the push-rod is v, the push rod 38 to its i to return the push rod to plement-al rail 45 is reached. The rod 38 is i then forced upwardly and by means of the connecting link 36 actuates the rock shaft 31 whereby the crank 32 is oscillated upwardly to elevate the coupling pin 35a.

Having Vfully described our invention what we claim is: y

The combination with a car having an en d extending base, therewith, a gravity operatedV pin having enthe draw-head, a vertical gagement with sleeve having at its opposite ends spaced' wings fitting on the upper of the end `extending base,

connecting said wings with ing base, a lower sleeve, angle braces conmeans rigidly nected with the lower sleeve. and the car, a

push rod extending through reciprocatory fork carried att-he lower end the sleeves, a
